Install Siri on iPhone 4 with iOS 6.1 - [Step by Step]

Install siri on iPhone 4 today is possible with iOS 6.1.1. I found a way to install on devices that it is not allowed by apple. This solution I was surprised, to do this you need to Jailbreak iPhone 4 on iOS 6.1.1 with Evasi0n tool and instal Cydia. If you not Jailbreak go to this link Evasi0n Jailbreak to make this. It possible to install Siri on devices that do not support it, for example to the first generation iPad and iPhone 3GS.
